The English adaptation of the Multivariable Multiaxial Suggestibility Inventory-2 (MMSI-2) is a valid and reliable questionnaire for assessing anomalous phenomena. Based on 613 English adults, the inventory has five macrofactors: Clinical Personality Tendencies, Anomalous Perceived Phenomena, Incoherent Manipulations, Altered States of Consciousness, and Openness. Clinical Personality Tendencies, Incoherent Manipulations, and Altered States of Consciousness together predicted 18.3% of the variance in anomalous experiences. Reliability was acceptable for some factors and excellent overall, but the authors recommend further research to improve the model's predictive quality.
